.To all whom t may concern: y

Be it known that we, MEREITT WESLEY PALMER, residing at Raymond, Montgomery county, Illinois, and CHARLES SEIGLE MUNRO, residing at Fairbury, in the county of Jeerson and State of Nebraska, citizens of the United States, have invented a new and useful Gasoline-Stove, of which the followingis a specication.

This invention relates to improvements in gasoline stoves; the objects in view being to provide a stove of cheap and simple construction; that will be safe and odorless; that will be economical in its operation and will thoroughly vaporize the gasoline before itsapproach to the burner pipe.

Other objects and advantages of the invention will appear lin the following description', and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawingsz--Figure 1 is a perspective of a gasoline stove constructed in accordance with our invention. Fig. 2 is a vertical longitudinal section. Fig. 3 is a detail in perspective of the evaporator. Fig. 4 is a detail in perspective of the burner. 5 is a vertical longitudinal section of the needle valve. Fig. 6 is a detail in section of the valve 27.

Like numerals of reference indicate like parts in all the iigures of the drawings.

1 denotes the stove-top, which is provided with the usual central opening 2, or several openings may be employed in accordance with tho number of burners with which the stove is to be provided. The top is supported by the usual standards 3, and the latter near their lower ends support the protector 4 and arebraced in any suitable manner as at, said standards below the protector terminating in suitable feet. Aring 6, having an annular series of prongs or fingers 7, is secured in the opening'2, as is usual.

7 designates a collar or bracket, whichris secured to the rear side ofthe stove-top, and in the same is supported the cylindrical outer evaporating case, 8, provided with the inclined bottom 9, disposed toward the stove. A hot-air pipe 10 leads from the lower end of 5o the casing Sand communicateswith the rear n Fig.-

Side of the hot-air chamberll, which extends forwardly under the burner opening and is provided at its top and bottom with vertically opposite openings, in which is seated the vertical burner-pipe, 12. The bottom of the hotair chamber in front of the burner pipe 12 is provided with a series of air-inlets 13, and in rear of the same with a large orlmain inletopening 14. The lower end of the burnerpipe is seated in a supporting ring, l5, from which at diametrically opposite sides extend supporting arms 16, which latter at their outer ends are bolted to a convenient brace 5. The upper end .of the burner-pipe is opened, and has swaged therein the burner 17. At its lower end the burner-pipe is provided 'with a contracted opening 18. f

' The burner consists of the annular perforated ring 19, which at its edge is turned to permit of the swaging 20, and at its center there is located in the ring the inverted conical portion 21.

In the outer casing S of the evaporator is seated an inner casing 22, the latter being of less diameter and height than the outer casing, so as to combine therewith to form an air space. From a point slightly above the bottom of the inner casing 22, which is cupshaped, there depends a collar 23, which is connected by the vapor-pipe 24, with the lower end of the burner pipe 12, said collar thus preventing the escape of oil into the burner pipe should the valve accidentally open when stove'is not in use.

A valve 26 is hinged over the opening 14 of the hot-air chamber, and has connected thereto a valve 26a' adapted to close the pipe 10 when the valve 26 opens, and a twin-valve 27 and 28 is hinged over the opening 18vand in front of the pipe 24 respectively, the valve 28 being designed to close the end of the pipe 24, while the valve 27 is designed to close the opening 18 of the burner-pipe. A bracket 29 is mounted at one side of the burner-pipe, and in the saine is pivoted thelever 30. The front end of the lever extends through a vertical slot 31, formed iu a depending standard 32, secured to the front end of the stoveLtop, which slot at its lower end is at one side pro# vided with a notch. or offset 33. The front IOO end of the lever is designed to move in this slot, and to be locked in a lowered position by being thrown laterally into the offset. When not engaging the offset, the lever is normally elevated through the medium of a coiled spring 24a, connected to the under side of the stove-top, and to the lever. A bell-cranked arm 35 extends rigidly from the under side of the valve 27 with which moves in unison the valve 28, and a connectingrod 39 is hinged as at 36 to the lower end of the arm andat its upper end hinged to the rear end of the lever 30. A rigid arm 37 depends from the valve 26 of the hot-air chamber and is hinged as at 38 to the upper end of a connecting rod 39, extending to and loosely connected with the lever 30.

The evaporator consists of a series of conical perforated evaporatin g-pi pes 40, the same being arranged in an annular series asshown,

around a central pipe, and the bases of the t entire series being inclosed by a band 4l.; The apices of the cones each has mounted? thereon a distributing cup 43, and the series o'f cones are connected immediately below the l The series of l pipes is surmounted by a'star-shaped spreading-.plate 44, the points of the star agreeing cups by perforated strips 43u.

with the number of cups and terminating each in a cup, as shown, to which the points are secured. The evaporator as thus con-` structed is removably mounted upon the cupshaped bottom of the inner evaporator 'casing, the spreading plate 44 of the evaporator being directly under the center of the removable lid 45, of the casing.

Thelid is centrally perforated and provided with a collar 46, rising therefrom, and :snrrounding the perforation, and above the same is `mounted on the collar the valve-body47, having the two inlets 48 and the central discharge 49, having the seat 50, said body be-l ing connected with the collar 46 bythecoupg In the bore of the valve is threaded 1 the needle `52, the upper end of which termil nates in a handle 53, below which is located inner casing to the burner-pipe, a hot-air ling 5l.

the adjustable stop-nut 54.

`To operate `the stovethe needle-valve is roi tated so that a supply of oil is permitted to iow through the inlets 48, down through the valve-seat, from which it is delivered upon the distribnting-plate'-44,from which the gasoline flows inthin streams and is conducted by the points of the plate to the series of cups 43, and from the cups is uniformly spread Aover the surfaces of the minutely perforated vaporizing pipes, said gasoline being thoroughly vaporized before reaching the bottom of the vaporizer or evaporator. The burner `is lighted -and the hot air generated thereby; ows from the hot-air chamber through the pipe l0, up into the space between the innel-and outer 'evaporator casing, and down through the evaporators to the vapor-supply l pipe V24, tothe burner-p`ipe, and up through the burner. To accomplish this the lever is drawn down and thrown into the notch or 0E- set, whereby it is locked, so that the valves 26 and 28 are opened and the valves 26 and 27 are closed. Vhen it is desired to shut off the vapor and cease the operation of cooking, the lever is released from the notch or oset, and elevated by thespring so that the valves 26 and 27 are opened and the valves 28 and 26a closed, thus shutting off the supply of hot air and vapor and extinguishing the fire. In this manner the air is permitted to pass up through the burner pipe and hot air chamber thoroughly cooling the burner, the pipe and the adjacent parts,and cutting off all communication with the evaporator, hence avoidall unpleasant odors.

The valves 26 and 28 are pivoted loosely to the stem connecting them with theirfcom# panions 26 and 27 respectively as indicated at 28, and when closed are cushioned in position, thus con ining the vapor in the vaporpipe ready for instant relighting, Aand preventing the escapeof `any odors.

From the foregoing `description it will `be seen that we provide a `stove adapted 'to economically and thoroughly burn 'gasoline oils,

and this in a safe manner, devoid of 'any d'an-` ger whatever, in that `a thorough evaporation of the 'oils'takes place `p1'evious"`to"the arrival thereof adjacent tothe burning point, or point of :combustion also 'that the stove will immediately cool after the fire is extinguished, whereby it is especially adapted for use in warm weather and climates. It will also be apparent that the stove "may be `readily cleaned and prevented from becoming foul, in that all of the parts are readily accessible, and the evaporator may Vbe removed and cleaned by inexperienced persons.
